Product detail
| Product code | Reducing valves DP27- Spirax Sarco |
| Applications | Steam Pressure Reducing Valve regulates the steam pressure downstream from the valve to a pre-adjusted set point value. |
DP27, Pilot operated - Medium capacity
The downstream steam pressure signal operates a pilot valve against an adjustable spring, which changes the flow to the main diaphragm. This modulates the main valve adjusting the flow to maintain the desired downstream pressure. There is virtually no offset between full and no load conditions.
Features & Benefits
- Extremely accurate
- Easy to adjust
- Multi-pressure types
- On/off capability
- Can also be used as a surplussing valve

Steam Reducing Station
Many industrial plants produce high-pressure steam for process work. In many of these plants, there is excess steam capacity available that can be utilized for other purposes, such as space heating, water heating, etc. Process steam is often generated at a higher pressure than can be used for the other purposes. Whatever the needs for lower pressure steam, a pressure reducing station will be required.
A pressure reducing station is more than just a reducing valve fed off a steam main. A properly designed and installed pressure reducing station takes into consideration velocity, good piping practices, and safety.
